Revolutions Per Minute: David Lang, John Sherba, Lincoln Mayorga

On this week's Revolutions Per Minute, Sarah Cahill welcomes a remarkable group of guests to the program.

In the first hour, Sarah will talk with Pulitzer Prize-winning composer David Lang, whose score to the new film "Youth" was just nominated for an Academy Award and John Sherba from the Kronos Quartet will be in the studio to talk about Kronos' upcoming festival.

Then in the second hour, pianist and arranger Lincoln Mayorga is coming to the studio to play some of his recordings and tell us about his studies with pianist Karl Ulrich Schnabel, founding a record label, and working with both classical and popular music.
